Chapter 8, Problem 34P

Interpretation Introduction

Interpretation:

The 3-D formula of the products when 1-methylcyclohexene reacts with the given reagents is to be written. The location of deuterium or tritium atoms in each case is to be designated.

Concept introduction:

Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles, which accept electron pair.

Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles, which donate electron pair.

Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction.

Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.

Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules.

Hydroboration-oxidation: An organic reaction in which the double bonds of alkenes or alkynes are broken by ${\text{BH}}_3$. In this reaction, carbon–carbon double bond has been replaced by a hydroxy group in order to form an alcohol in the presence of peroxide.

When ${\text{BH}}_3$ is added to alkenes, they undergo hydroboration and form alkylboranes and oxidize to alcohols on the addition of hydrogen peroxide.
